The style guides we mentioned above are full of really helpful advice for formatting, organizing and composing your code. But there are a lot of rules - it can be difficult to internalize them all. Linters are tools that will scan your code with a set of style rules and will report any errors to you that they find. In some cases, they can even auto-fix the errors! The following articles explain in more detail the benefits of using a linter while you code.

Prettier is awesome. It is similar to a linter, but serves a slightly different function. Prettier will take your JS code and then automatically format it according to a set of rules. Unlike a linter, it’s not looking for style errors, but specifically targeting the layout of your code and making intelligent decisions about things like spaces, indentation levels and line-breaks.
Using prettier makes coding faster and easier! You don’t have to worry about nailing things like indentation, or remembering every semi-colon because prettier will take care of those details for you.
